Hole centers in Base (all models)

The JET Model J-2221VS and J-2223VS drill presses feature manual speed control. Models J2232AC and J-2234AC have inverter speed control. This manual contains procedures for both speed control versions. The manual provides separate instructions when differences in operation and maintenance exist.

Refer to Figures 1 and 2 for key features of the drill press.

Operation and Set-Up

Securing the Base

The base of the drill press has four mounting slots; two slots on both sides of the base. The drill press should be level and rest solidly on the floor. Place shims under the four mounting slots in the base as needed to level the drill press.

When securing the base to the floor, apply even torque to the fasteners to prevent distortion of the base.

Figure 1 Figure 2 Drill Press Features Drill Press Features (Manual Speed Control Model) (Inverter Speed Control Model)

Raising the Drill Head and Table

The drill press is shipped with the table and drill head supported by wooden blocks near the bottom of the column.

The head is raised to the operating position using a strap and hoist, then secured to the column by tightening the hex cap screw. The table is raised to the desired position using the crank handle. See Adjustments section for more information.

Electrical Connection

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

Slide a grommet onto the cord to be installed later in the control box hole, to prevent stress to the power cord.

1. Bring the lead wires through the hole in the side of the control box and connect as follows (refer to Figure 3a):

2. If your incoming power is single phase, connect the two leads to L1 and L2, and the green ground wire to the grounding screw.

L1 L2 L3

Refer to the Wiring Diagram section for wiring information.

The Drill Press is not supplied with a power cord. To connect power, you may either install a power cord with a UL/CSA listed plug, or hard wire the machine directly to a service panel.

If the drill press is to be hard-wired to a panel, make sure a disconnect is available for the operator. (During hard-wiring of the machine, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the drill press will be connected.)

Manual control models: Model J-2221VS (1Phase) is pre-wired for 110 volts. Model J-2223VS (3-Phase) is pre-wired for 220 volts.

NOTE: If rewiring the J-2221VS or J-2223VS for alternate voltage, you must reconnect the wire on the LED display accordingly (Figure 3), in addition to changing the motor leads.

Figure 3

Inverter control models: Model J-2232AC (3Phase) is pre-wired for 220 volt only. The machine can also be run on 1-Phase power by hooking up the ground, L1 and L2 wires, as explained below.

Model J-2234AC (3-Phase) is pre-wired for 440 volt only.

To wire the drill press with inverter control: If using a power cord, strip back the cord until

about 3 to 4 inches of the lead wires are exposed.

Grounding Screw

Figure 3a

3. If your incoming power is three phase, connect the three leads to L1, L2 and L3, and the green ground wire to the grounding screw.

This drill press must be properly grounded. Make sure the green ground wire is secured to the grounding screw as described.

Make sure the power available matches the power requirement of the drill. When the drill is connected properly, the spindle turns clockwise in a conventional drilling rotation. If the spindle does not turn clockwise, disconnect the drill from the power supply and reverse two of the three power leads (except ground wire green).
